Rav Yitzchak Alfasi – ר’ יצחק אלפס(י) – known as the Rif (1013–1103), author of the immensely important Halachot ha-Rif, a proto-code and abridgement of the legal portions of the Talmud. The Rif was born in Algeria, studying in Qayrawan (Kairouan), and established himself in Fez, though he was impelled to flee and made his way to Iberia, eventually settling in Lucena and becoming the head of its renowned yeshiva.
